The engine for the "Mole" motor-cultivator: installation, repair, replacement

Motocultivator, like any other equipment, implies the need for timely maintenance and repair. If you do not intend to contact specialists and are well versed in mechanical engineering, you can detect the malfunction and restore the device’s performance yourself.

Fuel supply problem

To indicate that the engine for the “Krot” motor-cultivator is out of order may be the inability to start the equipment. The reason in this case may be the launch system. The master must determine the source of the failure, for this the condition of the spark plugs is checked . If they are dry, then this indicates that the fuel mixture is not pumped into the cylinder by the engine. This can lead to clogging of the hole in the gas tank plug, lack of fuel and the presence of foreign objects in the fuel supply system. A closed fuel supply valve may cause a malfunction.

Troubleshooting

If the engine for the “Krot” motor-cultivator does not start, then you need to open the fuel tank, empty the drainage holes from foreign objects, and also remove the fuel valve. Drain gasoline from the tank, and then rinse the inside with clean fuel. The master will have to remove the connecting hose, which is located on the carburetor side. These manipulations are necessary in order to blow it along with the jets without disassembling the latter. It is recommended that you use a fuel pump.

Engine malfunctions at start

If the engine for the Krot motocultivator does not start, despite the fact that the candles are wet, the problem with the failure of the ignition system may be that carbon deposits are present on the electrode electrodes. In this case, the operator will have to clean the surface of the candles using emery. After that, the elements are washed with gasoline and dried well. The cause of the problem may also be that the gap between the electrodes does not correspond to that recommended by the manufacturer. You can adjust the gap by bending the side electrode to the required size.

Additional causes of ignition failure

The engine for the Krot motocultivator may also not work for the reason that the candle insulators are damaged. This also applies to faulty wiring. These items must be replaced. The “Stop” key can be shorted to ground, in order to start the motor, you should get rid of the short circuit. The contacts of the squares of the candles may also be broken, if this condition is met, then the contacts must be put in order. The Krot motocultivator with a Honda engine may not start if the clearance between the starter and the magnetic shoe does not match the value mentioned in the passport. The starter will need to be replaced if defects have been detected on it.

Compression Disorder

During operation, the “Mole” motor-cultivator may require repair. Honda engine, for example, in some cases "pleases" with a violation of compression. In this case, it is possible to launch, but this process is rather complicated. The motor will work unstable, and it will not work to develop sufficient power. The cause may be the appearance of soot on the working surfaces of the valves. The exhaust valve is often deformed, and the piston rings wear out, all this leads to difficult start-up of the equipment.

Compression recovery

If you purchased a Mole cultivator, engine repair may be needed after some time. When the consumer is faced with the above problems, it is necessary to analyze what the state of the engine timing mechanism is. Parts on which the donkey deposit is to be cleaned. If some parts are damaged, they must be replaced. The operator should check how well the piston rings have been preserved. In the event of a malfunction of this unit, it will need to be replaced.

If you encounter such problems, and an excess of oil was noticed on the spark plug electrodes, then you most likely need to adjust the carburetor and replace the failed piston rings.

Engine installation

Installation of the engine on the Krot motor-cultivator can be carried out independently. However, it should be understood that if the work is carried out without observing the technology, then an error can cause a quick failure of the equipment. In this case, you will encounter prolonged dysfunction of the device until the problem is fixed. If you do not want to lose the equipment so necessary for performing many tasks, then the work should be approached with responsibility.

At the first stage, torque is transmitted from the engine to the gearbox . The engine must be firmly attached to the frame of the structure or gearbox. For work, it will be necessary to buy a special installation kit that will allow you to mount the engine in place. A new engine will need to be fixed to the acquired site from the installation kit. At the next stage, the pulley is put on the output crankshaft of the unit. If you use the installation kit, you can install the engine in minutes. At the same time, it will be possible to use an imported motor by installing it on a unit manufactured by a domestic plant.

Carrying out engine replacement

Replacing the engine with a mole cultivator "Mole" is often enough done by users on their own. Initially, the equipment is equipped with a 2.4 liter engine. from. If the engine is out of order, and you can start it, but with big problems, sometimes an electric drill is used as a starter. If you encounter the described problems, which are complemented by the fact that the equipment stalls after heating, then the cause may be wear of the engine seal. If you have an old-style generator that is capable of producing 36 volts and has a power of 200 watts, you can use this engine as the basis of the device. He consumes about 3 liters of gasoline per hour.

Having cut the generator, you can remove the coupling with bearing and some part of the housing from it. A piece of the generator can be used as an adapter for the pulley of a cultivator. To form the second fulcrum, you can purchase Chinese bearings by attaching them to vertical bars. This element can simply be welded onto the axis of the former generator. Once a replacement for such an engine has been made, any gasoline can be used. As many users emphasize, in order to start equipment, even kerosene can be used. The maximum speed, of course, will be reduced, but it feels like torque will be greater. You should take into account that after this the noise level will increase, however, when using such a device, this is not critical. As with the "native" engine, the unit makes a lot of noise. Among other things, the manufacturer advises using headphones when working.
